T0 all whom it may concern:

Be it known that I, EDGAR RICHARD NVA- TERMAN, a citizen of the UnitedStates, residing at Helena, in the county of Lewis `and Clarke and Stateof Montana, have invented a new and useful Oil-Burner, of which thefollowing is a'speciication.

My invention is an improved oilburner especially adapted for use as anattachment for ordinary cooking-stoves, ranges, and heaters, and to burnoil, either crude, refined, or distillate; and it 'consists in thepeculiar construction and combination of devices herein after fully setforthl and claimed.

In the accompanyingdrawings, Figure 1 is a' perspective View of myimproved oil-burner,

showing the same as'an. attachment to an ordinary cooking-stove. Fig.`2is a top plan View showing the top plate of my improvedl burner. Fig. 3is a vertical sectional view of my improved burner, taken on a planeindicated by the line a a of Fig. 2. Fig. 4 is a top plan view showingthe bottom plate and the generating-cone formed thereon. Fig. 5 is adetail elevation of the clamp for connecting my improved oil-burningattachment to a stove. Fig. 6 is a detail'perspective view. Fig. 7 is adetail sectional'view showing the proiles of the generating-cone and thedared opening in the top plate". Figs. 8,9, 10, and 11 illustratemodifications of my improved burner. y

In the embodiment of my invention I provide a top plate 1, which ispreferably cir'cular-in form and is adapted to be substituted for one ofthe removable lids of an ordinarycooking or heating stove or range. Ashere Shown, the said top plate is'provided on its' under side with anannular rabbet 2 ofsuch width that the top plate is adapted to beused onstoves of various sizes, the said rabbet` adapting the top plate to beplaced in or on a stove-lid opening of any size. The s aid top plate isprovided with a feed-pipe3,which extends from a reservoir 4 to containthe oil. The end of the feed-pipe 3, Where-the same is connected tothetop plate, is bent upwardly and then vdownwardly to form a siphon vorgooseneck 5, and the said pipe is preferably provided with a valve 6 tocut off or permit Owing to the curvature 5 in lthe said pipe 3, thesupply of oil to the burner inthe lower side of the top plate 1. g 12 orother suitable devices are employed to secure the said hangers to theunder side kof ceases assoon as the valve 6 is closed, as will beunderstood. The inner end of `the feedpipe 3 is connected to an opening7 in the top plate 1 at a suitable distance from one side of the latter,and near and on opposite sides of the said opening 7 are air-inletopenings 8, which may be of anysuitable form, but are preferably of theform shown in Fig. 2. I also provide a bottom plate 9, which ispreferably of the form shown in'Figs. 3 and 4 and has its upper sidedished or concaved, as at 10.A The said bottom plate is formed withhangers 11 on its upper side, which are approximately of conical formand the upper ends of which are adapted to enter recesses Screws the topplate, and thereby connect thebottom plate thereto in such manner thatthe-bottom plate may be readily removed fromv the top plate whendesired. On the upper side of the bottom plate, at a point immediatelyunder the opening 7, is a generating-cone 13, which is formed integrallywith the bottom plate and is truncated, as shown. The upper portion ofthe said generating-cone is disposed in a downwardly-tlared opening 14,with which the top plate 1 is provided, which opening 14 forms anextension or lower continuation of the e said opening 7, and it will beobserved by reference to Fig. 3 of the drawings that a slight annularchannel 15 is formed between the said flared opening 14 and the upperportion'of the said generating-cone. The latter iis' provided withradially-disposed grooves 116, which are formed on its surface andextend-from the base thereof to its apex and serve to conduct the oilfrom the pipe 3 downwardlyon the said generating-cone toward the bottomplate.

' In operation when myimprovedoil-burner is in use as an attachment to astove air is drawn downwardly through the openings 8 in the top plate,which openings, being disposed near opposite sides of thegenerating-cone, cause the air to unite with the vapors or gases fromthe oil and cause the same to be Aconsumed. It will be understood thatowing to the heated condition of the parts of the burner the oil, whichis supplied to the apex of the generating cone, is converted into ICOgases or vapors while passing downwardly in the channel 16 of saidgenerating-cone, and hence the oil is entirely consumed as it is fed tothe burner. The concaved or dished upper side of the bottom plate adaptsthe same to hold a small quantity of oil, to be ignited for the purposeof initially heating the burner before the same is started in operation.

My improved burner is adapted for burning crude oil as well as refinedor distillate oil, and in the practical operation of my burner I findthat the same does not become clogged with carbonaceous residues, andhence does not require to be cleaned and requires practically noattention when in operation.

An annular plate 17, provided on its under side with radially-disposeddownwardly-extending tongues 1S, is adapted to be placed around thegenerating-cone and to rest on the bottom plate at the base of said conefor use in summer.

The base of the generating-cone is hollowed, as at 19.

Owing to the fact that the air which becomes carbureted and consumed bythe burner is supplied to the same through the openings 8 inthe topplate when my improved burner attachment is in use in connection with astove or range, the burner is entirely l unaffected by outside drafts,no matter in rated, recess 25.

what position the stove may be placed 0r to what drafts it may beexposed, and hence there is no danger of the ame becoming extinguishedand the burner becoming hushed by the escape without the consumption ofthe oil. Furthermore, all odors incident to the burning of the oil areconfined to the interior of the stove and the flue, and none of theodors escape and become offensive in the room in which the stove islocated.

In connection with my improved oil-burning attachment I provide a clamp,which is shown in Fig. 5, for supporting the feed-pipe 3 and thereservoir and enabling myimproved burner attachment to be readilyattached to or removed from an ordinary stove. The said clamp comprisesan outer section 20, an inner section 21, and a set-screw 22, whichconnects the same together. The outer section 20 is of approximatelysemicircular form and has a pair of upwardly-extending jaws 23 24. Thelatter is wider than the former and is provided with a semicircular,preferably ser- The said inner section 21 is formed on one side with ahook 26, which overhangs the recess 25 and the lower side of which iscorrespondinglycurved and serrated, as at 27. The opposite side of theupper portion of said inner section 21 is formed with a jaw 28, whichsomewhat overhangs the upper end of the jaw 23. The feed-pipe 3 isdisposed in the recessed opposing sides of the jaws 24 26, the flange ofthe stove being engaged by and between the jaws 23 28, and by tighteningthe set-screw 22 the said clamp may be thus readily attached to thestove in position to support the feed-pipe 3 andthe reservoir, as willbe readily understood. Furthermore, by slightly loosening the set-screw22,so as not to disengage the clamp from the flange of the stove-top,the feed-pipe 3 will be turned axiallyin the recesses 25 27 of the jaws24 26 to enable' my burner attachment to be raised from thestove-opening in which it has-been disposed and turned to one side ofthe stove-top, as will be understood from an inspection of Fig. 1. Theset-screw is here shown as provided with a winged head to enable it tobe readily turned by the thumb and forefnger. The outer section 2O has aslot 20a, in which the shank of the set-screw operates, thus enablingthe section 21 to be adjusted laterally, as may be required in theoperation of the clamp.

By the use of the annular plate 17, which, as before stated, is designedfor summer use, the effective superficial area of the cone may bediminished, as said plate when seated on the base of the cone has theeiect of reducing the height of the latter. Hence the size of the flameproduced by the action of the burner is diminished when the plate 17 isused. Furthermore, the use of the said plate 17 enables the burner to bemore readily started in operation, as said plate becomes initiallyheated very quickly. Said plate also acts as a delector or spreader.

In Figs. 8 and 9 of the drawings I show a modified form of my inventionespecially adapted for use for heating purposes in connection withheating-stoves, furnaces, and small boilers. In this form of myinvention the door A of the stove or furnace forms the body of theburner and is cast with a box B, which projects from the outer sidethereof, and the bottom of which box forms the bot- IOO tom plate orsupport for the cone or cones, y

of which any suitable number may be used. The top or cover C of the boxhas an outwardly-projecting flange D at its outer side. The clamps whichsecure the feed-pipe 3 engage said flange. Said top or cover also hasthe draft-inlet openings Sformed therein. In this form of my inventionthe reservoir 4:, as well as the pipe 3, may be supported by the clamps,or the reservoir may be provided on one side with a vertically-disposedstrip E, projecting above and below `the reservoir and having a circularopening e in its lower projection and an opening e', enlarged at itslower side, in its upper projection, to enable the reservoir to besupported on a wall or partition of a room by headed nails or screws. InFigs. 11 and 10 of the drawings I show, respectively, a boiler-furnaceand a range provided with a door, in which my improved burner isincluded.

Having thus described my invention, I claim- 1. A burner of the classdescribed, comprising a top plate; a feed-pipe discharging through anopening therein 3 said top plate being further provided with air-inletopen- IIO- ings; and a bottom plate, suspended below and supported bythetop plate, concaved on its upper side and having a generating-conedisposed with its apex under the discharge of the feed-pipe,substantially as described. 2.
